To all whom it lmay concern;

Be it known that I, WALTER. R. JOHNSTON, a citizen ofthe United States,'and residing at New `York,v in the county of New York and State of yNew York, have invented' certain new and useful Improvements in Fire-Extinguishing Engines, of which the following is a specification, such as will enable those skilled in theV art to which it appertains Tto make and use the same. Y

This invention relates to engines for use in extinguishing fires, and t-he object thereof is to provide an improved portable engine of this classl which is designed to contain a suitable chemicall compound for use inextinguishing firesv and which may be used in a variety of wavs by meansof difl'erent elements contained `in and lforming a part of the engine..

M v improved engine involves a lbucket of novel construction and provided with a cover having at one edge thereof and fiush with one side of the inner wall of the bucket an opening having a hinged or movable cap and means for sea-ling t-he same, said bucket being also designed to 'contain a. chemical compound employed, and being provided with a pump whereby saidcompmmd may be thrown aconsiderable distance, and said bucket being also provided with a number of supplemental elements which areI placed therein and .which may be separately used for the purpose of extinguishing fires, and which are normally filled with the chemical compound and ready for use atall times, and which mayv be removed from the bucket whenever necessary through the opening in the cover thereof.

The invention is fully disclosed in the following specification, of which the accompanying drawing forms a part, in vwhich Athe separate parts of my improvement areA deslgnated by suitable reference characters in each of the views, and in which Figure 1 is a plan view of my improved a side view thereof; ,a sectional plan view,showingthewcover removed and showing Vthe supplementalfire extinguishing elements placed thereinuFig. 4 a vertical section on thenline 4-4 of Fig. 1 andshowing the cap of the opening` in the top of the bucket raised; Fig. 5 aside and sectional view of cooperating parts of the pump operating devices; Fig. 6 a sectional side view Specification of Letters Patent.

of a valve device which forms a part of the pump mechanism and showing also a side view of a locking key by which the valve is operatechsaid key being connected'with the piston rod of the pump mechanism when in use; and, Fig. 7- a view similar to Fig. 4 but" showing a modification thereof,

In the practice ofmy invention l provide a bucket ay having a stationary cover a2 andin one side. of which is an opening ai shown in full lines in 4 and in dotted lines in Fig. 1, and said opening is provided with a and around the opening a3 which 1s irregular in form as shown in 1, are collars or flanges at, and the cap b is provided with corresponding collars or flanges b2 which fit iu the grooves formed by the collars or flanges d4, and said grooves formed by the collars or flanges at, in practice, are illed with a composition of infusorial earth and vaseline so as to form a seal for the cap b. The side ,of the bucket adjacent to the opening c in the cover thereof is so formed that the inner wall of the bucket is flush with the outer edge of said opening, and said outer edge of said opening is circular in forni or corresponds in shape with the said side of the bucket at the top thereof in order to vfacilitate the discharge of a part of the conf'v tents ol the buca et. in the use of' the appa-I ratus as hereinatter described. .The sta-' tionary coverf'vo'f -the bucket is also pron vided with a. circular opening a-5`closed by 'fa'A cap c, said cap being held in place by screws" c2, and around the opening a5 are annular grooves a. formed by corresponding collars or flanges, and the cap c is providedwith corresponding annular flanges c3 which it in said grooves, and in practice, the' said grooves a are filled with a composition of inusorial earth and vaseline to form a seal varound the opening aff l 'The cap is tubular member ci" in which is secured a pump cylinder a in which is placed a valve pistond provided with a rod d3 which passes upwardly 'through the cap c and around the opening in the cap c through which the rod d3 passes is agland colla-r e in which is secured a gland e2, land the collar e and the gland e2 form a stufling box Jfor the rod di* on the outer sides of which are inclined ribs e4 formed on the collare, and one of which is shown in full lines in Fig. 5 and both of which is shown in section in Fig.- 4. The collar e -is also proprovided with a depending` 10 a cap f on the inner side of whi collar c, vand said ca is also provided on one side of the outer side thereof with parallelribs f3, shownin full lines in Figs.- 1 and 6 y1li and in section in Fig. 4. The pistondis provided Lwith ports or assages d4 and laced on said 4piston is a exible lflap valve 55, and said ports or passages d* are opened Twhen the piston d2 is moved downwardly and 1240 closed 4 by thel valve d5 when the piston d2 is moved upwardly. Y l

In the botto portion f the pumpcylinder d is. secured afoot valve g having ports or passages and aced overthe same is a flap-valve whic oprifteswinuthe same manner as thevalv d5, and around the bot-f jtom of the pump cylinder d are'llateral ports 4or passages g4 preferably inclosed by. a wiregauze.. screen or similar 'guard g5.

.30 Therlpper end or top .of the piston; d2 is i provide aboveV the cap f with a handle d and 'Said cap is rigidly secured to said rod and moved therewith, andfsaid'rod and cap f may also be rotated in which operation the piston d? is .also i'otated, and when thev engine is not in use the piston d2 is forced downwardly 'into its lowermost position in which o eration the cap j' incloses the collar e, an said 4 l rod Vand cap are then turned so as to lock the 40 ca fon said collar by means of the above re erred to locking devices e4 and f2, and'in this position of the parts the port or passage e3 in the collar' e is closed, the object of the ortcor passage'le3 being to admit air to the 45 ucket or receiver when the pump or engine is in use, and said Iport-or passage being sealedlby the cap fw en the. engine is not'ln use.

On one side of the cap c is a raised stud h havin a horizontal passage. h2 in which is 'place' a threaded ta ered valve plug i, and

. the stud his provide with a port or passage 'hsfand the tapered valve plug/i with a horizontalr port or passage 'i2 adnapted to com- .5'5 municate` therewith, and said valve plug is also provided with a collar i3 having a pin itfwhich normally fits in the roove formed by the ribs f 3 on the outer'si e of the cap'f, aladin the operation of securing said cap to Athel collar c ashereinbefore described, the vvalve plug i is turned so as to close the port .or passage ha, and in detaching said cap f from the collar Ve and raising the piston d2 the Vsaid valve plug is turned so as to open said port or passage. 'f

vbe

The threaded portion ofthe tapered. valve plug i fits into a smooth tapered valve casing formed by the stud h and the screw threads on the valve plug i are filled with a compound of infusorial earth and vaseline for the purpose of more thoroughl sealing this j'oint and prevent the escape o gas from the bucket at this oint, or the admission of air thereto, and a though I have. specified the yuse of'unfusorial earth and vaseline as a sealing medium, my invention is not limited thereto andl any suitable 'material maybe employed. The valve plug 'i is also provided at one end with a coupling collar i5 'with which in practice is connected a bent connection'j to which is attached a liexible tube c through which, in iractice, the contents of the bucket may be iorced to a considerable distance, and said tube in practice, is providedwith a dischar'fg'e nozzle, not shown,

which may be manipu ated in the manner of other devices of this class.v Wir'ithn the bucket a is also laced and. normally kept a plurality of supp emental devices or'elements which may be used forthe purpose of ex'n tinvuishing fires in' a room, compartment, or bui ding where said fires can be conveniently got at. One of these supplemental elements or fire extinguishers consists of a syringedevice m which may beinserted into the bucket through the opening a3 and removed therefrom whenever desired, and said s ringe device is made in the manner of other evices of this class such as the Little Giant for which Letters Patent of the United States' were granted to me on the 28th day ofApril, 1896, No. 558,959, or in they manner of a similar device shown and described in an ap lica tion for Letters Patent of the United fild by me December 7, 1905,' Serialy No.

290,706; and. another of said elements consists of a cup n 'provided with a handle n* and in which is inserted Va supplemental cup 11,3, in which is inserted a tubular cup n* provided AwithA a perforated' and removable cover a5.

In practice all the supplemental fire extates tin uishing devices m, 1a/Aa and n* .are norma ly filled readv for use at all times, and- 115 either or all of them may be removed from the bucket for use whenever desired. The

o eration of-the syringe' device m will be' similar to that of all other devices ef this class, while by means of the `cups n andl3 l quantities of the lire extinguish-ingcomposiion maybe thrown bN hand on a fire, and. whenever it` is not deslred todisehargelarge quantities vof the f ire extinguishing compound at a single .operation the tubular cup n-havlng a perforated covern5 ma be' used, and

cipient ot at. I y means of the construction hereinbefore e' located at any point where it can -described,I provide an engine for extinguishing fires capable of a large variety of uses and` one which may be conveniently carried about from point to pointand by meansof whicha fire extinguishing liquid or compound may be thrown by means of a pump to a considerable distan'caand when it is not desired to usev the pump orwhenlthe fire is located in a small space, room or compartment land may be conveniently 'got at, any of the supplemental devices contained inthe bucket may be used.

Ther ermanent cover ofthe bucket is also provlded with -an opening closed by athreaded cap Q or in any desired way, the object of sind opening being to provide means for test-4 ing the contents ofthe bucket without breaking theseal formed by the caps d and c, 'and extinguishing engine is the same as .that used in what 1s known as the Little Giant fire extinguisher, hereinbefore referred to, and

- thisl compound Ais such that only a small quantity need be used, a small amount thereof being suiicient to put out any ordinary fire at the start, said compound expanding into a gas of many times the volume of the com-- pound when thrown into the fire, which-gas extinguishes fthe fire. The chemical com-I -pound -Which I" employ will not injure theands of yanoperator', or garments, ory any textile material on which it may be thrown,

and if in jxcase'a fire has gained considerable Vmy improved fire engine-as shown 1n Figs.

headwayin a room or o her compartment, the movable cap b may e opened or raised "as show-n` in Fig. 1 and .the supplemental fire 'I extinguishers within the bucket may be re- Inovedan'd the contents of the bucket, or a 'art thereof, may bethrown bodily into the e .through the openingca', this operation being performed by grasping .thebail k2 inv Qnehand and the bottom-edge ofthe bucket i 4'5 at one 'sidef'thereof'in the'fQther hand, and in orderto facilitate the operation-of the pump .which 4fornfls the main' part of my improved fire engine I'plaCe beneath the bottom ofthe bucket aslide 7c3 having a handle member kt,

and-said'slide mayl be drawn 'out from be- ;n'eath the bottom of;the.bucket, and in 'ractice one foot.' is placed thereon' so las to oldthe bucket-down in the operation 'of using the pump, and if desired the bottoni of I Cn the bucket may be provided at the two opposite sides witha similar device for a similar purpose, or an i suitable means may be )rovided 'on whic the feet may be place to l Vhold the bucket down in the operation of the 60- pump. Y

It will be understood that the pumping part of the engine may be used `whenever necessary without breaking the seal formed by the cap t or without opening said cap, and it will also be understood that. by openbucket may be discharged through the opening a3 in the mannen above described, and the supplemental fire extinguishing devices placed in the bucket may b e removed at this time and separately used if desired, but it will be apparent that as far as the pumping part of my improved engine is concerned, the said engineer device! may be lused independently of the supplemental fire extinguishing devices which fare placed in the bucket, and my invention is not limited to the use of said devices.

ln Fi 7 I have shown a modification in which t ie bucket is provided with alpermanent cover having a central opening around which is a downwardly or inwardly directed annular flange or rim member p having a depending central tube member p2 with which the pump cylinder d is connected, and the opening in the cover of the bucket is closed by the cap c the same, or substantially the same, as shown in- Figs. l and4, and it will be understood that with thisconstruction all the parts of the pump device or apparatus shown in Figsl and 4 are employed, the /objectof Fig. 7 of the drawing being to show a modification of the bucket in which the supplemental Vfire extinguishing devices are not employed' and the cover of the bucket not provided with anv openinga's. The apparatus shown in Fig. 7 being intendedto` illustrate a device in .which only the pump is employed.'

By means of the method of constructing described, it will be apparent that the en.-

gine or apparatus, o r lthe pump i feature thereof, may be continuallyv operated and new materlal may be poured lnto the bucket lwithout stopping -the operation of the pump,

and after the composition used in the buckety or receiver is exhausted, if no Inore is con-' vement, water may be vpoured into the bucket or receiver and forced through the pipe le for the purpose of extinguishing the fire. lt will also be apparent that while the engine or apparatus herein shown and described is designed'to be operated by hand the same maybe made so that the pump mayl be operated by power if desired. .It Will also be observed that in Fig. 4 of the drawing the handle d by which the pump is operated is formed integrally with the piston rod d3, and the ca p f formed separately and secured to said rod, but in the construction shown in Fig. 7 the handle d is formed integrally with the cap f, and this construction is also shown ing said cap any part of the contents of the in Figs. .5 and 6, but it will be understood that either the construction shown in Fig 4 or that shown in Fig. 7, in this respect. may

be elnployiid.

5 The bucket which forms the main and inclosing part ol my improved fire engine ma) be provided with straps p" as shown in Fig.

7 by which it may be carried from place to place, or said bucket may be provided with 10 both a bail k2 and stra-p pi, and various changes in and modifications of the construction described may be made without departing from the spiritI of 1n v invention or sacrificing its advantages.
